Medieval soldier found with sword and knives at the bottom of a Lithuanian lake

More than 500 years ago, a medieval soldier’s dead body settled at the bottom of a Lithuanian lake, and for centuries it lay hidden beneath the mud. Now, those submerged remains have finally been found. The skeleton was discovered during an underwater inspection of the old Dubingiai bridge in eastern Lithuania’s Lake Asveja. Though the […]

Primeval Greenland lake found buried beneath a mile-thick slab of ice

Scientists have discovered an ancient lakebed buried under more than a mile of ice that may hold secrets to Greenland’s past climate.  The lake formed when northwest Greenland was ice-free, sometime between hundreds of thousands or even millions of years ago. Given Greenland’s rapid melt today, the lake could reveal something about the Arctic’s future […]

Mystery of glacial lake floods solved — ScienceDaily

A long-standing mystery in the study of glaciers was recently — and serendipitously — solved by a team led by University of Hawai’i at Manoa astrobiologist and earth scientist Eric Gaidos. Their findings were published this week in the journal Geophysical Research Letters. The mystery involves floods or “jokulhlaups” that emerge suddenly and unpredictably from […]

Future lake food webs in subarctic have more biomass and contain more omega-3 fatty acids

In northern lakes algal and fish biomass are increasing with temperature and productivity. At the same time, fish communities are changing from whitefish towards roach dominance. Credit: Kimmo Kahilainen & Brian Hayden Subarctic regions are facing rapid changes in climate and land-use intensity. An international research team recently completed an investigation to see how these […]
